Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature.
A first direction
The first direction and the film length direction of the tearing layer form any included angle, namely the first direction is consistent with the film length direction of the tearing layer, or is arranged in an acute angle or an obtuse angle. When the double-sided tape is used by combining foam cotton to form the double-sided tape, in order to smoothly tear and pull the strip-shaped unit tear tape away from the outer side edge of the workpiece, further, the first direction and the film length direction of the tear layer form an acute angle, and the acute angle is 0-15 degrees. In order to facilitate the processing and simplify the production process, further, the first direction is consistent with the film length direction of the tearing layer.
Tear strip
The surface of the tearing strip is a rough surface, so that the adhesive force with the foam layer is increased on one hand; on the other hand, when the end part of the tearing strip is connected with the tearing extension section in the reworking process, the bonding firmness of the tearing extension section and the tearing extension section can be increased.
The long edge of the tear strip is provided with a thinning edge, and the thickness of the thinning edge is gradually reduced from the tear strip main body to the side edge along the parallel direction.
Release layer
The easy-to-tear glue is separated along with the release layer. The foam is prepared on two sides of the tearing layer at intervals by foaming from the release layer. The setting of easily tearing off glue ensures that difficult breaking away from in the foaming raw materials foaming process, improves the processing stability.
Foam double-sided adhesive tape
The cotton layer of bubble includes the cotton layer of first bubble and second bubble, tears the layer and foams earlier and form the cotton layer of first bubble dorsad from the surface on type layer, tears and leaves the type layer, and the surface foaming who tears the cotton layer of layer dorsad first bubble forms the cotton layer of second bubble, and the cotton layer of first bubble and the cotton layer dorsad surface of tearing the layer of second bubble all set up the adhesive linkage.
Example 1
As shown in fig. 1~6, in the composite film with a tearable layer of embodiment 1, the tearable layer 1 includes a first surface and a second surface along a thickness direction, the first surface is provided with a release layer 2, and the tearable layer 1 and the release layer 2 are connected by an easy-release adhesive 20. Tear layer 1 includes a plurality of tear tape 10, and the length of a plurality of tear tape 10 extends along the first direction, sets up side by side between the adjacent tear tape 10, and the first direction is unanimous with the long direction of membrane of tear layer 1.
A space 11 is provided between adjacent tear strips 10, the spacing between adjacent tear strips 10 being less than the width of the tear strips 10.
The material of the tearing layer 1 is PET polyester. The thickness of the tearing layer 1 is 12 μm, the thickness of the release layer 2 is 50 μm, and the thickness of the easy-release glue 20 is 20 μm.
The width of the foam double-sided tape is 6mm, and the width of the tear tape 10 is 0.6mm.
The foam double-sided tape comprises the composite film with the tearing layer, the two surfaces of the tearing layer 1 are respectively provided with a foam layer 3, and the surface of the foam layer 3, which is back to the tearing layer 1, is provided with an adhesive layer 4. The bonding layer 4 is connected with the workpiece, and the foam double-sided tape can be used. When the foam double-sided adhesive tape is not adhered to a workpiece or the workpiece is damaged, reworking is carried out, the edge of the tearing layer 1 is torn to form an independent tearing strip 10, and a tearing extension section 101 is arranged at the end of the tearing strip 10, so that subsequent tearing work is facilitated.
Example 2
As shown in fig. 7, example 2 is based on example 1, except that the lengths of the tear strips 10 extend in a first direction, adjacent tear strips 10 are juxtaposed, and the first direction is disposed at an acute angle to the film length direction of the tear layer 1.
The structure that the cotton double-sided tape of bubble was applied to on the tear layer of embodiment 1, when carrying out the operation of doing over again, set up tear extension section 101 at the tip of independent tear strip 10, tear extension section 101 including pulling section and canned paragraph, press to locate the canned paragraph through pulling the section and form and pull the cutting power, phase separation between the tear strip 10 will be more smoothly, and with the cotton cutting of strip bubble in the interval 11, and then realize tearing the layering on the cotton layer 3 of bubble about 1 and reach the purpose of doing over again, reduce the work load on the cotton layer of bubble of manual division among the operation of doing over again, make the operation of doing over again more swift convenient.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
